Problems solved by technology
The commonly used trapping fish system is very imperfect, and it is very unfriendly to fish in front of and behind the dam, which may easily cause unnecessary damage or death of fish
At present, a set of trapping fish crossing dam system structure can only be operated by one method, which is very limited in the choice of methods, and cannot adapt to various changes such as large and small numbers of fish

Embodiment Construction
[0048] See figure 1 , figure 2 , image 3 shown.
[0049] A fish trapping system suitable for mountain rivers in a fish lift project, the fish trapping system according to the present invention includes a fish trap 1, a fish collection channel 10, a fish catching grid 3, a fish collection pond 11, and a lifting device;
[0050] The fish luring mouth 1 is set near the bank of the dam, at the edge of the mainstream;
[0051] A fish-collecting channel 10 and a fish-collecting pond 11 are arranged sequentially inwardly from the fish luring mouth 1;
[0052] An anti-escape grille 2 is set in the fish collection channel 10 close to the fish luring mouth 1, and the escape prevention grille 2 includes a large mouth position and a small mouth position, and the large mouth position is close to the fish luring mouth 1;
[0053] A fish-catching grid 3 is arranged inside the small opening of the anti-escape grid 2, and the fish-catching grid 3 is set to open and close the grid so as t...

The invention relates to a fish trapping system suitable for mountain rivers in fish elevator engineering and a method. The fish trapping system comprises a fish trapping opening, a fish collecting channel, a fish driving fence, a fish collecting pond and a lifting device; the fish trapping opening is formed in the position close to the bank side of a dam and at the edge of main flow; the fish collecting channel and the fish collecting pond are sequentially arranged inwards from the fish trapping opening, and so on. The fish trapping system is scientific in structural arrangement and obvious in fish luring effect, downstream fishes migrate to the bottom of the dam and then are lifted to the upstream part in a very short time through mechanical control of the fish trapping system, almost nomechanical damage is caused to the fishes in the period, and a very positive role is played in ecological protection construction of the downstream part and the upstream part of the dam; the engineering construction price of the system is relatively low, the system can be universally applied to river basins with various widths and depths, and the size can be further improved; and more importantly, the system provided by the invention can be applied in two modes of natural trapping and flowing water suction, and the application conditions are more variable.
Description
technical field [0001] The invention belongs to the technical field of fish trapping system structures and methods, in particular to the technical field of fish trapping system structures and methods suitable for mountain rivers in a fish lift project. Background technique [0002] Existing dams must consider the construction of a fish passage system during design, and the fish lift project is just one of the systems. The fish lifting machine project is built between the upstream and downstream of the dam. It is one of the large-scale projects and the cost is very huge. The construction of the dam will have a certain impact on the local ecology, especially on the biological habits of various fish spawning and migrating in the upstream and downstream mainstreams and tributaries. In order not to break the balance of the local ecological chain, it is necessary to The fish machine engineering is supplemented by trapping fish systems and devices to improve its ecological functio...
